Abstract

Breathable, water resistant protective articles, such as garments, sleeping bags, and the like, which are readily packable into small volumes. The articles are constructed from an outer layer comprising a laminate of a textile bonded to a barrier layer, an insulation layer and an inner layer comprising an air permeable textile.

Claims (43)

1. An article comprising:

(a) an outer layer comprising a laminate of a textile bonded to a barrier material, said laminate having a water leakage of about 1 g/H 2 O or less after 40 hours of washing, a breathability of about 1000 g/m 2 /24 h or greater and an air permeability of about 0.3 cfm or greater;

(b) an insulation layer comprising a synthetic fiber insulating material; and

(c) an inner layer comprising an air permeable textile,

wherein said article has a packing volume of 600 in 3 or less.

2. The article of claim 1 , wherein said outer layer has an air permeability of about 0.8 cfm or greater.

3. The article of claim 1 , wherein said outer layer has an air permeability of about 4 cfm or greater.

4. The article of claim 1 , wherein said inner layer has an air permeability greater than the air permeability of the outer layer.

5. The article of claim 1 in the form of a garment.

6. The article of claim 1 in the form of a sleeping bag.

7. The article of claim 1 , wherein said article has a durable water leakage of less than about 1 g/H 2 O after 40 hours of washing.

8. An article comprising:

(a) an outer layer comprising a laminate of a textile bonded to a barrier material, said laminate having a water leakage of about 1 g/H 2 O or less after 40 hours of washing, a breathability of about 1000 g/m 2 /24 h or greater and an air permeability of about 0.3 cfm or greater; and

(b) an insulation package layer comprising an insulation layer comprising a synthetic fiber insulating material oriented between two air permeable textile layers, said insulation package being quilted together,

wherein said article has a packing volume of 600 in 3 or less.

9. The article of claim 8 , wherein said outer layer has an air permeability of about 0.8 cfm or greater.

10. The article of claim 8 , wherein said outer layer has an air permeability of about 4 cfm or greater.

11. The article of claim 8 , wherein each of said textile layers of said insulation package has an air permeability greater than the air permeability of the outer layer.

12. The article of claim 8 in the form of a garment.

13. The article of claim 8 in the form of a sleeping bag.

14. The article of claim 8 , wherein said article has a durable water leakage of less than about 1 g/H 2 O after 40 hours of washing.

15. The article of claim 1 , wherein said article is in the form of a sleeping bag has and has a packing volume of 500 in 3 or less.

16. The article of claim 1 , wherein said article is in the form of a garment and has a packing volume of 300 in 3 or less.

17. An article comprising:

(a) an outer layer comprising a laminate of a textile bonded to a barrier material, said laminate having a water leakage of about 1 g/H 2 O or less after 40 hours of washing, a breathability of about 1000 g/m 2 /24 h or greater and an air permeability of about 0.3 cfm or greater;

(b) an insulation layer comprising a synthetic fiber insulating material oriented adjacent said barrier material; and

(c) an inner layer comprising an air permeable textile, wherein said article has a packing volume of 600 in 3 or less.

18. The article of claim 17 , wherein said outer layer has an air permeability of about 0.8 cfm or greater.

19. The article of claim 17 , wherein said outer layer has an air permeability of about 4 cfm or greater.

20. The article of claim 17 , wherein said inner layer has an air permeability greater than the air permeability of the outer layer.

21. The article of claim 17 in the form of a garment.

22. The article of claim 17 in the form of a sleeping bag.

23. The article of claim 17 , wherein said article has a durable water leakage of less than about 1 g/H 2 O after 40 hours of washing.

24. An article comprising:

(a) an outer layer comprising a laminate of a textile bonded to a barrier material, said laminate having a water leakage of about 1 g H 2 O or less after 40 hours of washing, a breathability of about 1000 g/m 2 /24 h or greater, and an air permeability of about 0.3 cfm or greater; and

(b) an insulation package layer comprising an insulation layer comprising a synthetic fiber insulating material oriented adjacent an inner air permeable textile layer, said insulation package being quilted together,

wherein said article has a packing volume of 600 in 3 or less.

25. The article of claim 24 , wherein said outer layer has an air permeability of about 0.8 cfm or greater.

26. The article of claim 24 , wherein said outer layer has an air permeability of about 4 cfm or greater.

27. The article of claim 24 , wherein each of said textile layers of said insulation package has an air permeability greater than the air permeability of the outer layer.

28. The article of claim 24 in the form of a garment.

29. The article of claim 24 in the form of a sleeping bag.

30. The article of claim 24 , wherein said article has a durable water leakage of less than about 1 g/H 2 O.
